The 2017 Survey of Construction (SOC) from the Census Bureau shows that the average completion time of a single-family house is around 7.5 months, which usually includes almost a month from authorization to start and another 6.5 months to finish the construction. The average completion time in 2017 was the same as it was in 2016, but it was longer than the time needed in 2015 (7 months).
The time from authorization to completion varies across the nation and depends on the geographic location, metropolitan status, and whether the house is built for sale or custom-built. According to the 2017 SOC, it takes anywhere from less than a month to 77 months to build a single-family home from obtaining a permit to completion.
